Special display cases to be custom-made on request according to special exhibits or special exhibition.Museum display cases with immense size,abnormal shape like column,trapezoid shape or particular function like zero oxygen internal display environment can be customized as per actual requirements.No any compromise on the security,stability and airtightness come to special display cases.
For special museum display cases,the glass panels are still made by 3-ply laminated safety glass which meets BS EN356 Part 4A,the international authoritative criteria of safety glass.Optiwhite glass with low iron content or ultra clear glass with low reflective coat ensures high light transmittance with no vision distortion.Frameless construction and invisible glass bonding bring no any sight obstruction on display.UV bonding adhesive under advanced UV bonding technology and dedicated cure agent make glass hood elegant but solid.Specifications of glass like 4+0.76+4,5+0.76+5,4+1.52+4,5+1.52+5 is usually proposed or 6+1.52+6 or 8+1.52+8 for larger sizes of display cases..
Same as standard museum display cases,the metal profile of specially-customized display cases to receive glass panels is made by dedicated powder-coated aluminum extrusions and then tightly secured to structural steel skeleton that is made by mild/low carbon steel and powder-coated for finish.
Inert materials are comprehensively used for making display cases,no any chemical or oxidation reaction will take place inside internal display volume.All the adhesive,sealant and cure agent for bonding are neutral and non-hazardous,MDF panel for structural backboard and dressing baseboard contain zero folmaldehyde and fully sealed by aluminized polyethylene film before being veneered with environmental fabric,therefore no destructive pollutional VOCs will come up and bring any possible damage on exhibits including sensitive artifacts.
Dust-free design to prevent air pollutant from entering into internal display volume. Limited air exchange to create well airtightness, usually not more than 0.1 per 24 hours, bewteen outside surrounded atmosphere and internal display volume within display cases.
Unless specified,shelving system for special display cases in irregular construction usually come with three options,i..e.fabric-dressed ZF-MDF baseboards or steel decks in powder coating finish for shelving platform,or backboards to be mounted with shelving system,or a suspending shelving system with height-adjustable toughened glass shelves for flexible display.
LED lighting system such as LED spotlights, LED light panels or combination or fiber optic lighting system are applied to different designs of special display cases.
Usually pull&slide opening system or hinged opening system is applied to special display cases.
